itcampbell Ahhh, that makes sense. Pretty sure I only have one connection. It's a non CA bike. I'll stuff it back in there. Glad it wasn't something super important! Thank you all for your help!

CheapBassTurd No octopus parts or it can get really interesting. LOL

GoMotor The vent tube from the back of the tank just hangs down with the other open ended tubes and is open at the end.

I think the idea is that if any liquid gas gets past the little valves of the vent system in the gas cap, it will go through the little nipple on the right under side of the cap into the internal line in the tank and out the back and down to the ground.

The catch is that on non California bikes that nipple is not sealed and the leaked gas can go wherever gravity and the wind take it. On California bikes it is sealed and the piping leads into a vapor recovery pollution control system.

And hang down through a hole? Yeah, that's the missing hose's connection. Nothing is connected to that nub on my bike.
You just have one attachment at the back of the tank, yeah, not two? (My bike is equipped with CEB (California Emissions Bullshit), so I get two tubes out the back.)

I don't actually know how that routes on a non-CEB bike. GoMotor?

Once I had a fuel hose on one of those split open. Things were getting damp with gas from sloshing a full tank. Fun. Sliced it down and managed to create enough slack to get it reattached, salvaging the weekend.

Now, reattaching. Is this just supposed to hang down through that hole there, or does it need to attach to something or be secured in a specific spot?

Thanks all!

Not that one (that one's the vacuum to the petcock), but this one off the carb, attached to this point:



(Someone correct me if I'm wrong, but I think that's the one that routes down, not back.)

I have the T-mod in there, so your tube routing might be slightly different.

The battery tube is on the side of the battery, like so:



Hopefully that's the one that's gone missing.

GoMotor You did not mention #4 that goes to the rear of the gas tank under the front nose of the seat. It is the vent line for the gas tank. I wonder about it's value since on non-California models the exterior nipple on the gas cap that connects to the part of this line inside the tank is not sealed.

itcampbell Thanks for the reply! I don't see any bare nipples on the left side, or anywhere else (but I haven't removed the seat or anything yet, either, for what it's worth..

Nope, that guy's accounted for.

Based on the info you provided me, I bet it is the battery hose. Two years ago I replaced the stock battery with a sealed one. Had it replaced, rather, and I'm not sure how the dudes who replaced it had it connected on there or whether they even left it fastened on. But assuming they did leave it just hanging out would explain why I can't find any place that's missing a hose, and would explain why it jostled off so easily. I've put about 8K miles on it in that time.

Thanks for your help!!

Tube #3 is not capped and slightly larger in diameter than the other two tubes. No idea what this tube is for.
The three dangling tubes go to the following (parts listed are for a 1995, which is what I have):

Carb, part 92059A (I think?):

Airbox, part 50144:

Battery, part 703:

http://www.kawasakioemparts.com/oemp...ical-equipment

I still have a battery tube on mine, but my battery is sealed so the tube's just sitting there open at both ends. The way the battery one routes for me makes it seem unlikely that it would just fall off; indeed, it has gone thousands of miles not attached to anything, and stays well-put.

On the carb, look on the left side and see if there's a 90 nipple just hanging out on its own.

Let us know what you find; always curious about things like this.
